Chapter 1 As organizations continue to decentralize and outsource non-core functions to suppliers, it’s essential to establish trust between partners and have transparency in data management to ensure data security and privacy IAM is a technology framework that helps organizations ensure that the right people have access to the right resources. IAM includes two main functions: authentication and authorization. IAM capabilities have become the central pillar for cloud-based scenarios A crucial piece of an IAM solution is its life cycle management capabilities. Microsoft Cloud Adoption Framework (CAF) provides a set of best practices, guidance, and tools for different stages of cloud adoption, from initial planning to implementation and optimization it is not just for Azure, it can work with  Amazon Web Services (AWS) and Google Cloud. includes a specific IAM design area that focuses on providing guidance and best practices for designing secure and scalable IAM solutions Azure AD sup...

Title: Designing Data-Intensive Applications Author: Martin Kleppmann Publication date: March 2017 Print length: 616 pages Chapter 1 Thinking About Data Systems There are datastores that are also used as message queues (Redis), and there are message queues with database-like durability guarantees (Apache Kafka). The boundaries between the databases, queues, caches, etc. are becoming blurred Increasingly many applications now have such demanding requirements that a single tool can no longer meet all of its data processing and storage needs. Instead, the work is broken down into tasks that can be performed efficiently on a single tool, and those different tools are stitched together using application code. If you are designing a data system or service, a lot of tricky questions arise. How do you ensure that the data remains correct and complete, even when things go wrong internally? How do you provide consistently good performance to clients, even when parts of your system are degrad...

Title: Building Microservices, 2nd Edition Author: Sam Newman Publication date: August 2021 Print length: 612 pages Chapter 1 Microservices are a type of service-oriented architecture.  Deployability is key for a microservices. to ensure independent deployability, we need to make sure our microservices are loosely coupled Having clear, stable service boundaries that don’t change when the internal implementation changes results in systems that have looser coupling and stronger cohesion. Model services around business domains it will make it easier to roll out new functionality and to recombine microservices in different ways to deliver new functionality microservices should be slices of business functionality that encapsulate user interface (UI), business logic, and data Microservices should avoid the use of shared databases if a microservice wants to access data held by another microservice, it should go and ask that second microservice for the data Microservice should be kept...
